SN74F08DBR

Overview

The SN74F08DBR is a quadruple 2-input positive-AND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74F logic series and utilizes a 14-pin SOIC surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a low-level output current of 20 mA, a high-level output current of -1 mA, and a propagation delay of 6.6 ns. It supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Contains four independent 2-input AND gates for complex logic implementation
• Provides high-speed signal processing capabilities typical of the F series
• Features robust low-level sink current capacity for driving loads

Applications

• Digital logic circuits requiring multiple AND operations
• Data routing and selection systems
• Control logic in industrial instrumentation

Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SOIC-14 package and tape-and-reel delivery format. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the supplier provides documentation verifying the manufacturer as Texas Instruments to avoid counterfeit parts. Check that the operating temperature range aligns with your system's thermal environment.

Selection Notes

Select this component when high-speed performance is required alongside standard TTL-compatible voltage levels. The 74F series offers faster switching speeds compared to LS or HC variants but consumes more power. Consider the 14-SOIC package dimensions for PCB layout constraints. Evaluate the 20 mA output drive capability against the input requirements of downstream components to ensure proper signal integrity.

Part Context

This part is part of the widely used 74xx logic family, specifically the fast (F) sub-family designed for speed-critical applications. It serves as a fundamental building block for combinational logic designs. The SN74F08DR variant shares identical electrical specifications but may differ in packaging or reel configuration.

Replacement Considerations

SN74F08D: Identical function and package without the reel suffix.
